This invention relates to devices for holding two parts in setposition while they are being welded either bythe acetylene process or while they are being-electrically weld- 5 ed or otherwise treated. j.

The general objectof the inventionis to provide a table and clamps adjustable upon the table to any desired position having adjustable jaws whereby the two partsof the l article to be welded are held rigidly inposi- `tion against any `chance of relative movement. i H A further object is to provide .ai table so constructed that the clamps may he disposed l in any desired position thereon and provide clamps which are mounted upon upon brackets which in turn engagethe` table for swingingmovement in a horizontal plane. `A further object .is `to `provi-de brackets which will permit `the `claiups tobe" ad justed up or down and provide means `for holding the clamps rigidly in their adjusted positions. y ji Y Anotherobjectis to provide atableof :this character having means whereby a plurali-v ty of clamps may be disposed in a large ya riety of differently related positions so that the object tobe welded,isoldered. for otherwise worked upon` shall be rigidly held.`

My invention is illustmted'in` the accompanying drawings," wherein Figure 1 is atop plan view of the device; Figure 2 `is a bottom plan view of the table; v j

Figure 3 is an elevation of one of the clamps; i V

Figure 4 is a section on the line 4--4 of Fig. 3;

Figure 5 is Fig. 3;

Figure 6 is a lsection on the line 6-6 of Fig. 3; j i j Referring to thesedrawings. 10 designates the table which may be made of sheet metal and be supported upon legs or in any suitable manner.` `This table is preferably formed with areinforced rim 11 and transverse braces 12, the rim and braces being `formed with a plurality of holes 13. The

'a section on the line 5--5 of 4o f Coacting with the perforations 13 are .the

supporting brackets 14. These are formed j of strips of metal angularly bent at one end braces extend acrossthe under 'face of thef me?. semi n. maine.

j slot 16. i The reduced somewhat hook shaped extremity 15 is adapted lto be inserted into Fics..

any one ofthe perforations 13 and-to beroytatably adjusted yin `said j iertora'tions.` The hook shapedfextremity permits the bracket to be shiftedin any direction `into `angular relation ytol fthe table butthe weight of the clamping devices to be hereafter described willnormally 'hold this bracket `in a position at. `right angles to the-face of the table. Passing throughthe slot 16 of eachbraeket is a screw-threaded clamping rod 17 formed witha jaw 18 at oneend the inner face of this jaw being toothed. Coacting with the jaw 18 is a sliding jaw 19 having that face confronting the jaw18 toothed and jaw 19 is held iin its adjusted position by a nut 20 havbetween the nut `20 and the jaw 19. Also .mounted` `upon the screw-threaded. rod 17 are supporting 'bracket` firmly between them and as e consequence hold the supporting rod 17 in a vertically adjusted posit-ion upon the supporting bracket. When the nut 20 is turned up it will force thejaw 19 against ring Aa handle. A washer may be `disposed i the object held between the jaws 18 and 19.

Thus these jaws may be clamped securely uponthe object to be supported.

l The pirmary object of this invention is to provide means whereby the sections lof a part to be weldedlor otherwise joined may be held `in proper abutting position with the broken surfaces or the` surfaces to be t welded in contact with eac-h other. I have illustrated in Figure 1 the manner in which bracket 14, the rod 17, the clamping nutsV 21, `the clamping jaws 18 and 19 and the clamping nut E20. These clamping sets may be disposed in any desired position upon the table vand lwhen clamped in position will hold the article to be welded lirmlyin place against any accidental shifted movement so that the workman can Weld, solder, or otherwlse 'act upon these parts. The clamping sets are particularly adapted for use 1nv clamping articles having amore or less l.ir regular format-ion which would be extreme 1y difficult to clamp or holdin an abutting position by any other means than that dis closed. yIt will be understood that as many The rod 17 is more or lessrectangular in Y cross sectioniso that the collars at the ends ofthe jaws may have sliding'engage'ment on the rodin rotative engagement therewith. The rod is rotatively adjustable in the slot 16. l f

1. A welders table vhaving a plurality kof perforations through it. supporting brack ets, each having an vend adapted to be enjgaged with the tablel through one of said perforations, each bracket being longitudinally slotted, a screw-threaded 'rod passing through the slot of each bracket,` clamping nuts engaging the rod and adapted to engage in each side of the bracket to hold'the rod in adjusted position, clamping jaws carried by the rod, the jaws being relatively shiftable toward or from each otheryand .means for holding the clampingjaws in adjusted position.

2. A welders table having a plurality of perforations through it, and work holding means-comprising a bracket having one end formed to engage with any one ot said perforations,.the bracket being vertically slotted, a screw-threaded rod passing through the slot ofthe bracket,'clamping bolts on the rod in vertically adjusted position, the rod being formed at oneend with a' jaw, a jaw slidingly mounted'upon the rod toward and from the fixed jaw,"and a nut'operatively engaging the last named jaw to hold the.

and clamping jaws carried onthe rod, one

of said jaws being adjustable toward or from the other jaw. i f t 4. A welders table having a plurality of perforations, a work supporting devicel including brackets each having one end reduced to pass through a perforation and angularly bent, clamping rods vertically and longitudinally adjustable upon the brackets, and clamping jaws carried by said rods and relatively adjustable toward or from each other.

In testimony whereof I hereunto ax my signature. j
